OK - I went ahead and upgraded to 1.13.
Guess what? No Integrated option
I found a rather unusual thing. Previously I had set a password for my harddisk. It was same as my boot password and the old BIOS never asked me for the HD password, only the boot. I thought it automatically tries the same password on the HD.
BUT, the new BIOS actually asks for the HD password separately! That makes me wonder if the old BIOS was even honouring my password. Then again, as far as I know the HD password is stored in the HD itself (it's actually a feature of the HD). So how can the BIOS bypass it. I'm not sure, I'm just trying to make sense of my observations. Any insight would be good to hear.
NOTE: I also noticed a slight jump in my power consumption - it could be paranoia =p
